# CHISQ.INV

CHISQ.INV(probability, degrees_freedom)

Returns the inverse of the probability distribution function for a chi-squared distribution (left tailed).

 probability The probability associated with the distribution. degrees_freedom The number of degrees of freedom.

 REMARKS
 * This function was added in Excel 2010 but it does not replace the CHINV function because this was right tailed.* The chi-squared distribution is a [[continuous distribution]]* If "probability" < 0, then #VALUE! is returned.* If "probability" > 1, then #VALUE! is returned.* If "probability" is not numeric, then #VALUE! is returned.* If "degrees_freedom" is not an integer, it is truncated.* If "degrees_freedom" < 1, then #NUM! is returned.* If "degrees_freedom" > 10^10, then #NUM! is returned.* If "degress_freedom" is not numeric, then #VALUE! is returned.* You can use the CHISQ.DIST function to* You can use the CHISQ.DIST.RT function to* You can use the CHISQ.INV.RT function to* You can use the CHISQ.TEST function to* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com
